Ken Sunshine told "Access Hollywood" that it was not true that Affleck and the 33-year-old star of the she-spy TV series "Alias" said "I do" at a hush-hush wedding out of the media spotlight.
Rumors of the Hollywood nuptials broke on Saturday when a florist and wedding planner in Wheeling, W. Va., told The New York Daily News that Garner had ordered a bridal bouquet and six bridesmaids' bouquets for a late-night ceremony at the posh Greenbrier Resort (search) in the Allegheny Mountains.
Brandon Tucker, who owns the Briarwood Flower Shoppe, said that Garner wanted the bouquets to include ivory Virginia roses, Casablanca lilies and gardenia.
"I was just dumbfounded," Tucker told The Daily News. "In Wheeling, not too many celebrities come in. I should have worn something different."
The rumor mill has been working overtime on the celebrity couple, who met on the set of the 2003's comic book-based action flick "Daredevil."
Gossip Web sites and tabloids have buzzed for months that Affleck proposed to Garner at her birthday party last April, and that the pair are expecting a baby, which is due sometime in November.
Publicists for both stars have categorically refused to comment on the report, but Garner has been spotted wearing a 4.5-carat Harry Winston diamond ring in recent months and appears to have gained some weight around her middle.
So far, the low-profile couple have managed to keep the nature of their relationship under wraps, appearing publicly together only once at the 2004 World Series in Boston.
The never-married Affleck's relationship with pop star Jennifer Lopez was the favorite fodder of tabloids until the pair split in 2003. The 'Bennifer' breakup came just days before they were scheduled to walk down the aisle in a lavish ceremony in Santa Barbara, Calif., and was a media sensation. Garner divorced actor Scott Foley in March of 2004 after four years of marriage.
Affleck, 32, is currently filming "Truth, Justice and the American Way," a biopic on the life and mysterious death of 1950s "Superman" star George Reeves.
Garner, whom Forbes magazine recently rated as the fifth best-paid actress in Hollywood, is filming a romantic comedy, "Catch and Release," and is working on the fifth season of "Alias."
